Human health and environmental impacts of coal

2018-1-1  Due to its high energy generation potential, coal is widely used in power generation in different countries. Although, the presence of carbon, hydrogen and sulfur in coal facilitates the energy generation in coal combustion, some pollutants including COx, SOx, NOx, particulate matter (PM) and heavy metals are accumulated in air and water and lead to severe

Gallium - Wikipedia

2021-2-20  Gallium is a chemical element with the symbol Ga and atomic number 31. Elemental gallium is a soft, silvery metal at standard temperature and pressure; however in its liquid state it becomes silvery white.If too much force is applied, the gallium may fracture conchoidally.It is in group 13 of the periodic table, and thus has similarities to the other metals of the group,

Nuclear power - Wikipedia

2021-2-19  Nuclear power is the use of nuclear reactions that release nuclear energy to generate heat, which most frequently is then used in steam turbines to produce electricity in a nuclear power plant.Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by

Coal - Wikipedia

2021-2-20  Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Pore Distribution and Variation Rules of the Coal

2021-2-4  Micropores play an important role in gas adsorption and migration. To reveal the variation rule of coal structural parameters in nanosize at different CO2 adsorption pressures, a CO2 adsorption in situ small-angle X-ray scattering test is performed in this work. The results show that the adsorption at different pressures somewhat influences the pore diameter

Coal in China - Wikipedia

2021-2-20  Coal mines in pre-industrial China. Ancient people in current China started using coal around 6 000 years ago. Historians suspects that the Chinese were involved in the surface mining of coal around 3490 BC, pioneering the pre-modern world. Fushan mine uses to be pointed out as the earliest coal mine in the ancient world and started around 1 000 BC.
